20. The golden rectangle Follow these instructions to construct your own golden rectangle. 1.Draw a square of any size. 2.Mark on it the midpoint of the base, X. 3.Extend the baseline. 4.Open up your compasses. Put your compass point on X and pencil point on A. Draw an arc to the baseline. 5.Construct a perpendicular from Y, where your arc meets the baseline and finish off your rectangle. ●Repeat this for three different starting squares. ●For each one of your constructions, find the ratio length : width.

22. The Golden Ratio Golden ratio (phi or φ) or 1.618033989……. Try calculating Φ² and 1/ φ n th term of the Fibonacci Sequence = φ n /√5

24. a = top-of-head to chin b = top-of-head to pupil c = pupil to nose tip d d = pupil to lip e = width of nose f = outside distance between eyes g = width of head h = hairline to pupil i = nose tip to chin j = lips to chin k = length of lips l = nose tip to lips

25. The Golden Ratio, Art and Beauty The ratio of the width of the nose to the width of the mouth in a beautiful face is 1:1.618, the Golden Ratio. Now take the distance from the hairline to the tip of the nose and then the distance between the nose and the chin. The ratio on an attractive face will be… you guessed it, 1:1.618. So, the more beautiful a face, the more it will fit in the mask. From Queen Nefertiti to Greta Garbo to Cindy Crawford, beautiful faces fit within the measurements of the mask almost exactly. Even Jessica Simpson, while some people may question the beauty of her music, seems to have a face that fits the geometric proportions of the Golden Ratio.
